Personal preference... What is the best tens machine, and dumb question, how often do the pads get changed out?
I got mine from Walgreens. Orion I think is the brand. Pads last for 150 uses.
I have a tens unit I had ordered from Amazon several years ago, it works great! It's small but works great! I change the pads when they get hair stuck to them or don't stick good anymore!!!
Oh wow. Ok cool
So they can be used multiple times... How long do you wear it?
